The Harvest of Taiwan Star Hunting Trip

After a week back from Taiwan, I have just finished processing all the raw deep sky objects’ images. As a novice in DSI and an illiterate in processing DSI, I spent extra time to refine the images. Perhaps the quality of the images are average, I learned a lot and received positive feedbacks from other stargazers. The sky in Hehuan Mountain (合歡山) was not as dark as expected. It was much better than the sky of Hong Kong already. There were too many stars in the sky and made me difficult to identify the constellations. Gorgeous! The spectacular Milky Way was engraved in my mind and it was the second time I saw it. I was told that the sky in Australia is extremely dark. The Milky Way is able to cast you a shadow. I have put Tasmania in my vacation list. Hope to visit Tasmania in near future. Anyway, these are my harvest:
